MOLD-JACKET.

Specification of Letters Patent.

Patented Sept. 5, 1911.

Application filed May 6, 1911. Serial No. 625,605.

To all whom it may concern:

Be it known that I, LON KIMBALL, a citizen of the United States,residing at Fort Smith, in the county of Sebastian and State ofArkansas, have invented certain new and useful Improvements in Mold-Jackets, of which the following is a speci-' and end plates, and aclamping frame adapted to press and hold the sides of the jackettogether; and an important advan tage of the construction is that thetop plate and sides are loosely connected and will accommodatethemselves to slight variations in molds, incident to variations in sizeof flasks.

A further novelty of construction is that the various parts areseparable, so that clogging is prevented, and bursting of the mold willnot destroy the efiectiveness of the jacket for further use.

Various other advantages will be apparent to those skilled in the art,from the structure as disclosed in the following specification and theaccompanying drawings.

In the drawings,Figure 1 is a perspective view of the jacket, in closedposit-ion. Fig. 2 is a perspective view illustrating the 7 applicationof the jacket to a mold, as the jacket is about to be put in positionand be fore it is tightened on the mold. Fig. 3 is a plan view of thetop plate. Fig. 4; is a perspective view of one of the end plates. Fig.5 is a detail in section of the clamping frame.

Referring specifically to the drawings, 6 indicates a top plate which ismade with openings 7 for gating the casting in the mold and for allowingthe escape of gases from the mold, as well as to lighten the structure.This plate is provided at its edges with extendlng eyes or loops 8,which serve the purpose of connecting the sides and ends to the topplate as hereinafter described.

The side plates are indicated at 9 and end plates at 10. These platesare preferably cast with openings 11 therein to lighten the jacket andallow the escape of gases. Each side and end plate is provided at itsupper edge with hooks 12 which are adapted to fit into or through theeyes 8, the points of the hooks being directed outwardly. The eyes aresomewhat larger than the bodies of the hooks, so that the latter willhave a certain amount of play in the eyes, in order that the walls ofthe jacket may accommodate themselves to slight variations in the sizeof the molds. When the parts are assembled the side and end plates aresupported by or hang from the eyes at the edge of the top plate, in aloose manner, and the shape of the hooks 12 is preferably such that theplates will tend to swing or open outwardly to a certain extent, inconsequence of the point of suspension being slightly offset from theplane of the plates, when the hooks are resting on the eyes. Each of theside and end plates is made or provided with external inclined or wedgeshaped ribs 13, extending vertically, and conveniently positioneddirectly under or forming a continuation of the hooks referred to,although this particular arrangement is not essential.

A clamp or binding frame 14 extends around the wall of the jacket, andthis is of such proper size that its inner edge rests against the ribs13, and when pushed down the wedging action of the ribs presses theplates together, and against the sides of the mold on which the jacketis placed. When the binder frame is lifted it contacts with theunderside of the eyes 8, and thereby supports the jacket when it isbeing placed on or removed from the mold, as shown in Fig. 2, in whichposition, as above stated, the plates will tend to swing apart sllghtlyso that the jacket may be readily placed upon or drawn from the mold.The blnder frame 1 1 is thus confined between the extended eyes on thetop plate and the lower part of the inclined ribs, and hence after theparts are once assembled they are all held together without possibilityof accldental separation.

In order that the binder frame may be put in place, it is necessary thatsome of the ribs .13 be detachable, and I have so illustrated the samein Fig. 4:, on one of the end plates,

the ribs being fastened to the plate by any suitable means, such asscrews 15. These screws may be taken out and the ribs taken off topermit the binder frame to be slipped on or off as necessary. After thebinder frame is taken off, the side plates can be detached from the topplate by swinging the former outwardly to drop the hooks from the eyes,but while the binder frame is in position it is impossible to detach theparts.

In the use of the device, the flask having been removed from the mold,the jacket is lifted by means of the binder frame, permitting the wallsto open or swing outwardly and the jacket is then lowered on or aroundthe mold. The frame 14: is then pressed down, and by contact with thewedge correspond to the mold or flask.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent is 1. A mold jacket comprising a top platehaving eyes at the edge thereof, adjustable sides having hookedprojections engaging in said eyes, and a frame extending around thesides and adjustable to clamp the sides against the mold.

2. A mold jacket comprising a top plate having projectin eyes at theedge thereof,

adjustable sides having hooks at the upper edge thereof loosely-engagedin said eyes, and a vertically adjustable clamping frame extending.around the sides and confined by said eyes when the frame is lifted.

3. A mold jacket comprising a top plate having eyes at the edge thereof,sides having hooks at the top edges thereof, extending through said eyesthe points of the hooks projecting outwardly and adapted to rest on saideyes, so that the sides will swing open when free, and a clamping bandextending around the sides and adapted to close the same.

4:. A mold jacket comprising a top plate having openings at the edgethereof, side plates having hooks at the top edge loosely engaged insaid openings, whereby the side plates are flexibly hung from the topplate, said side plates having inclined ribs on the outer side thereof,and a binding frame extending around the side plate and adjustable upand down thereon and confined between said ribs and top plate.

In testimony whereof, I afiix my signature in presence of tWo witnesses.

LON KIMBALL.
